This paper reviews the literature surrounding the use of Web 2.0 in education. It examines various perspectives of what Web 2.0 means, and how Web 2.0 can support a constructivist pedagogy. Case studies involving Wikis are examined and the problems experienced are considered from both a technological and a group-working perspective. The paper concludes that although Wikis have the potential to support social-constructivism the differences between artificially constructed learning groups (formal learning) and self-forming and emergent social groups (informal learning) result in a requirement for greater attention to the theories on group working when creating group tasks using Wikis for learning purposes. Wikis are a tool and do not, by themselves, result in satisfactory collaborationPeer reviewe
